Glad you're back up and running, and happy to help!
I was more thinking, do you have a computer with a floppy drive that you could use to write new floppies for your SD-1? Because in that case, you can create fresh floppies with the sequencer OS etc, since the disk images are available. I.e., you could replace (some of) your corrupted floppies with working ones. That would also give you back the sequencer in your SD-1, which is after all quite useful.
Or, if you're not really using floppies any more and would prefer to use something perhaps a bit more future-proof, you could replace the floppy drive with a floppy drive emulator - either an HxC Emulator that uses SD cards, or a Gotek Emulator with HxC firmware that uses USB thumb drives . Each stores floppy images on their respective medium (SD card or USB thumb drive respectively). Those floppy images can also be accessed if you connect the medium to your computer; that's how you would get images of the OS floppy into place, for example.
This would allow you to have literally hundreds of virtual floppies, including ones that are copies of the factory one(s), only a few button presses away and no longer needing the deteriorating actual floppies; and you could much more easily and quickly make or restore backup copies of everything you need.
Best wishes,
